The surface area of the cone is 
Explanation:
The diameter of the cone is 10 cms
Thus, the radius of the cone is given by

The slant height of the cone is 12 cms
The formula for surface area of the cone is given by

Substituting the values, we get,




Thus, The surface area of the cone is 
Answer:
2600
Step-by-step explanation:
2314 ÷ 89% = 2600
2314 is 89% of 2600.
D.
10>(12)-7(0)
10>12.... False
Refrection of a function across the y-axis, changes the sign of x in the function.
Thus, given the function:

Refrection of the function across the y-axis will result in the function:

Refrecting a function across the x-axis, changes the sign of the function.
Thus, refrecting the function:

across the x-axis will result in the function:
